Description

The Left Twin follows the shallow inside corner up to the small overhang. Once at the overhang either climb to the right and finish in the nook shared by The Right Twin, or climb the obvious outside corner to the left using ledges and cracks.

Protection

I went here a few weeks ago with my sister. It was an easy hike (we had a dog) and lots of good anchors for TR. Its always nice to find an area where we both can be challenged. If you start left of the left twin, you can make it a bit more challenging. There are plenty of ways to make any of the easier climbs on Birthday rock more difficult.

A couple loose blocks at strategic/crux locations. Be careful, but I truly think they have been loose for decades! One is a diagonal shaped block about half way up and is great for a lie-back. The 2nd one is toward the top and is about 1 to 1-1/2 foot tall little tower. It should only be used for a pull straight downward. An outward pull may lever it down on your belayer!

Led this route this past weekend. Shallow gear running down the middle seam, but good/small horizontal ledges to the left of the crack 25 feet up for secure feet. Easier led than Right Twin. But worth time to climb it.

This route felt like a 5.6 to me. There was no move on par with the difficulty of the crux of, say, Peter's Project or Birthday Crack to give it the 5.7 rating. I would even go so far as to say that this climb felt easier than Brinton's Crack and Pine Tree Step Across because the moves here were so obvious.
